This invention relates to an improved cleaner and feeder for use withcotton gins.

An object is to provide a new and novel arrangement of cylindricalbrushes which cooperate with a series of screens to convey cotton alonga circuitous path from the inlet to the outlet, each brush also actingas a fan to set up a circulation of air which, in cooperation with thecentrifugal action of the brush, effects a thorough separation of dirtand other foreign particles from the cotton fibre.

Another object is to provide brushes which include in their constructionrows of alternately arranged spikes and tufts of bristles, whereby thecleaner can be made without the separate spike drums commonly employed.

It has been found in practice that drums having spikes only beat andbreak the cotton fibres to an objectionable extent, thereby lowering thequality of the staple.

An object of the present invention is to avoid the objectionablecharacteristics of spike cylinders, by combining the spikes with thebrushes, thereby producing better results, each cylinder effectingcleaning by the use of brushes and spikes and by air currents set upthereby.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a side elevation of a portion of thestructure.

Figure 2 is a central vertical section therethrough.

Figure 3 is a longitudinal section through one of the cylinders, aportion being broken away.

Figure 4 is a plan view of one of the bars of the cylinder.

Referring to the figures by characters of reference I designates acasing having its bottom inclined downwardly to a trough 2 for receivingdirt and other foreign matter separated from the cotton, there being aconveyor 3 in the trough for withdrawing material therefrom. Supports 4can be connected to the casing and the top has a closure 5 which, whenopened, affords access to the interior of the casing.

An outlet spout 6 extends from one end of the: casing and openingdownwardly into the casing is a feed chute 'l containing the usualfeeder rolls 8 to be operated in any manner desired. A vent flue 9 opensfrom the top of the casing as shown.

A series of lower concaves in the form of screens H), II and I2 islocated in the casing and these screens extend from one side to theother of the casing. They are concentric with air inlets l3 and arejoined as shown at M. Screen l2 merges into an inverted concave screenl5 which, in turn is connected to an inverted concave screen It as shownat H. At N3 the screen l6 merges into a screen 19 which overlies aportion of screen I0 and extends up to one side of the outlet end of Ftfeed chute 1. Screen I0 is beneath the chute and extends up to theoutlet 6, and a portion of the breast 120.01 the cleaner as wellasscreen [9 are, like screen [0 thereunder, concentric with one. of theopenings I 3.

Bearings 21 in the form of spiders or cross frames, are secured acrossthe openings l3 and journaled in them are shafts 22. Secured to eachshaft are skeleton heads 23 through which air can circulate freely, andthe heads on each shaft have annular series of outstanding peripheralears 24 arranged in pairs and cooperating to provide seats. These seatshold the ends of spaced bars 25 secured therein and. cooperating withthe heads to form open faced cylinders 26, 21 and 28 respectively.Cylinder 26 is between and con centric with screens I0 and Is as well asbreast 2o. Cylinder 21 is between and concentric with screens II and I6while cylinder 28 is concentric with screens [2 and I5.

As shown, each bar has a row of tufts 29 extending outwardly therefrom.These are made of the usual brush material and are spaced apart toreceive between them short pointed spikes 30, one spike being locatedbetween every two tufts. The tufts extend close to the inner surfaces ofthe screens but are spaced therefrom.

The shafts and the cylinders thereon are rotated simultaneously in thesame direction as.

to cylinder 21, carried along screen II to throat 3i, transferred tobrush 26 and delivered along screen [0 to the outlet 6. During thiscircuitous passage of the cotton from the inlet to the outlet thecylinders act as fans to suck air thereinto and expel it between thebars whereupon it is dissipated within the casing and escapes throughflue 9 carrying with it any fine particles held in suspension. The bars,tufts and spikes also set A up a centrifugal action which tends to throwoff through the screens any foreign particles and these will accumulatein trough 2 and be carried therefrom by the conveyor 3.

It has been found that by locating the spikes f between and back fromthe free ends of the tufts,

they effectively comb through the cotton but do,

not tend to beat and break the same and reduce its quality.

What is claimed is: 1. A cleaner and feeder for cotton gins including acasing and having opposed concave screens arranged in pairs andproviding throats between the pairs, a cotton inlet and a cotton outletopening between the screens of one pair,,and a unit constituting abrush, spike cylinder and fan rotatably mounted between the screens ofeach pair, each unit comprising open heads, bars securedv to theperipheries of and connecting the heads, said bars being spaced apartand constituting fan blades, a row of spaced brush tufts on each bar,and spikes on each bar and shorter than the tufts, there being one spikebetween every two tufts.

3. A cleaner and feeder for cotton gins including a casing havingopposed concave screens arranged in pairs and providing throats betweenthe pairs, a cotton inlet and a cotton outlet opening between thescreens of one pair, and a unit constituting a brush, spike cylinder andfan rotatably mounted between the screens of each pair, each unitcomprising open heads, bars secured to the peripheries of and connectingthe heads, said bars being spaced apart, a row of spaced brush tufts oneach bar, and spikes on each bar and shorter than the tufts, there beingone spike between every two tufts, there being air inlets in the casingat the end of each cylinder, and an air outlet flue extending from thecasing.

4. A cleaner and feeder for cottongins including a casing havingopposedv concave screens arranged in pairs and providing throats betweenthe pairs, a cotton inlet and a cotton outlet opening betweenthe screensof onepair, and aunit constituting a brush, spike cylinder and fanrotatably mounted between the screens of each pair, each unit comprisingopen heads, bars secured to the peripheries of and connecting the heads,said bars being spaced apart and constituting fan blades, a row ofspaced brush tufts screens of the pairs and thence along the lowerscreens each said pairs to the outlet.
